Revealing single-phase multiferroic (MF) materials in conventional bulk oxides is an exceptionally daunting task. However, achieving strong magnetoelectric (ME) coupling at room temperature (RT) these even more formidable despite their envisioned applications multi-state memory storage devices, spintronics, magnetic field sensors, etc. The weak ME MF primarily due to the ferro/antiferromagnetic ordering observed very low temperatures, contrasting with ferroelectric typically discerned RT. These challenges can be effectively addressed by leveraging discrete molecular-based materials. Nonetheless, remain infancy polar point groups complexes. By overcoming hurdles through meticulous molecular engineering, we have unveiled a complex, [Co^III₃Dy^III(L)₆].4MeOH (Co3Dy), which exhibits unprecedentedly constant (α) value of 250 mVcm⁻¹Oe⁻¹ This robust or above RT presumably originates from between magnetostriction and phenomena paramagnetic Co3Dy complex. To demonstrate harness large α value, developed nanogenerator device using convert stray fields into electrical energy. produces output voltage ~ 430 mV current 0.3 µA under small AC amplitude 24.2 Oe.
